I found this on the Bay Area Craigslist and I was intrigued by the XR-1000 style dual side pipes. What model is this?

Hard to tell from the pic

 

looks mostly stock, those pipes are in the J&P catalog.

i would go see it in person and hear that knocking sound for yourself, it might not be worth it even for 2k

 

Thanks for the prompt (and excellent) replies and info. Yes, I'll pass... A few dollars more and you get something decent.
